Iron Heart IHSH-401-NAV Ultra Heavy Flannel Chalk Stripe Western Shirt - Navy

As heavyweight flannels go, the Iron Heart Ultra Heavy Flannels are the champs. They get softer with wear and will most likely outlast you and anything else in your closet. The UHFs are made of Aspero cotton - a naturally occurring wild cotton from the foothills of North East Peru. It's actually a tree (yes, a tree!) so it's one of the purest, most organic forms of cotton in the world. It cannot be mass produced and has been prized by the Peruvians for centuries for its softness, fineness, volume and strength. This season brings a non-check pattern, instead coming in a Wabash-style "chalk stripe" colorway. This fabric is created by dying the Aspero cotton indigo, with the contrast stripes stitched in during the weaving process.
